Postdoc in Applied Math- Numerical Analysis & Free-Surface Simulations (1.0 FTE)

We have a vacancy for a postdoc in Applied Mathematics within the new project “HiWAVE - Natural hazard prevention with adaptive hierarchical models”, funded by the Dutch Research Council (NWO) via the talent programme Vidi in the group of Assistant Professor Dr. Julian Koellermeier.

HiWAVE predicts free-surface waves by developing adaptive hierarchical models. A main novelty is to combine recently developed moment models with model adaptivity, i.e., using different model equations in different parts of the physical domain. This will be made possible using the hierarchical structure of the moment models. The outcome will be both accurate and fast reduced models that achieve high efficiency.

In collaboration with two new PhD students and the rest of the PI's group (4 PhD's + undergrad students), the postdoc is in charge of the model adaptivity aspect of the project. This includes the development and analysis of new numerical schemes to efficiently couple different models in the same simulation, for example, using a global multi-level method or local error-based control.

HiWAVE aims at a breakthrough in mathematical modeling of free-surface waves, shifting from case-specific models towards adaptive model hierarchies. The results are expected to have major impact in the field of free-surface flows, but also in other fields like gas dynamics or uncertainty quantification.

This postdoc position is within the mathematical modeling group of Assistant Professor Dr. Julian Koellermeier, embedded in the Computational and Numerical Mathematics research unit of the Bernoulli Institute for Mathematics, Computer Science and Artificial Intelligence. The project is set up to include interdisciplinary collaborations with other researchers from the fields of fluid dynamics, applied mathematics, or computer science.

This position gives plenty opportunities to develop your academic portfolio via:

- Significant impact and publication output as part of the NWO VIDI project.
- Visibility and networking opportunities via the project and the PI’s connections.
- Co-supervision of (under)graduate students and PhD students.
- Training programs that strengthen your skillset.
- Active participation in the institute’s seminars and meetings.
- The possibility for additional paid teaching duties.
